Attagenus Latr. 

 The prosternal process is wider between the coxae than in Novelsis, 

 though still very narrow, and the species are larger, stouter, more ob- 

 long and almost uniformly clothed with rather sparse dark and incon- 

 spicuous pubescence. The species are somewhat numerous but closely 

 allied among themselves, those forms which are apparently worthy of 

 distinctive names may be defined as follows : — 



Elytra deep black throughout, the head and pronotum concolorous 2 



Elytra rufous to piceous-black in color, the anterior parts frequently darker than the 



elytra 4 



2 — Elytra each with a small spot of white pubescence at the middle of the length and 

 at inner fourth of the width ; pronotum with three small and widely separated 

 areas of pale pubescence at base ; third joint of the male antennal club black, 

 as long as the entire remainder of the antenna and rather more than four times 

 as long as the two basal joints of the club combined. Length 4.0 mm.; width 



2.0 mm. Rhode Island pellio Linn. 



Elytra without paler pubescence at any part ; pronotum without pale hairs at the 



base 3 



3 — Pronotum coarsely and closely punctate, without subbasal impressions ; antennas 

 of the male nearly as in pellio ; pubescence fulvo-piceous in color. Length 3.3 

 -4.0 mm.; width 1.6-I.9 mm. Indiana and California; \megatoma Fabr.]. 



piceus Oliv. 

 Pronotum very finely and less closely punctured, with three widely separated subbasal 

 impressions; body more broadly oblong-oval, shining; legs piceous, the tarsi 

 ferruginous, pubescence blackish ; last joint of the female club more than one- 

 half longer than the two preceding combined ; male not observed. Length 3.8 



mm.; width 2.0 mm. Idaho ( Cceur d'Alene) schaefferi Ilerbst 



4 — Pronotum not impressed, or clothed with paler pubescence along the basal sinua- 



tions 5 



Pronotum feebly impressed along the broadly rounded basal sinuations, the impressed 



margin clothed with finer and pale pubescence 9 



5 — Entire upper surface dark piceous-brown to piceous-black in color ; pronotum 



with a feeble subbasal impression before the scutellum 6 



Elytra bright red, sometimes narrowly infuscate along the suture, the head and pro- 

 notum black and much more closely punctured, the ante-scutellar impression 



not visible 8 



6 — Last joint of the male antennal club black, about as long as the entire preceding 

 part of the antenna, which is testaceous, and slightly more than three times as 

 long as the two preceding joints combined ; body moderately stout, oblong-oval, 

 legs ferruginous throughout. Length $ 3.2, O 3.7 mm.; width $ 1.7, £1.85 



mm. Pennsylvania extricatus, sp. nov. 



Last joint of the male antenna much shorter than the entire preceding part 7 



7 — Male club stout, the last joint two and one-half times as long as the two preceding 

 combined ; prothorax of the male fully twice as wide as long. Length $ 3-25, 

 9 3-4-3-7 mm -; width $ 1.6, O 1. 65-1. 85 mm. New York, District of Co- 

 lumbia and Virginia (Norfolk) deficiens, sp. nov.
